SPECIFICATION forming part of Letters Patent No. 322,163, dated July 14,` 1885.

Application filed May 21, 1885. (No model.)

' To. all whom. it may concern.-

Be it known that I, HIRAM B. Davis, a citizen of the United States, residing at St.l?aris, in the county of Champaign and State of Ohio, have invented certain new and useful Improvements in Whiffletrees; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use 'the same.

The object of this improvement is an economically-constructed, convenient, and durable device of reliable automatic operation for securing the connection of traces with whifletrees. These results are attained by the mechanism illustrated in the drawings herewith filed as part hereof, in which the sameletters of reference denote the same parts in the different views.

Figure lis a plan, with parts broken away, representing a tracesecuring device embodying the features of my improvement. Fig. 2 is a side elevation, partly in section.

A isa section of a whiffletree. B is a casting having a barb-shaped end, b b', and an adjacent circular formation, b2, all madehollow for the purpose of fitting over the whifdetree,and being provided inside Vwith a spring, C, having an inclined head,G,which projects through a correspondingly-sized opening provided for the purpose in the top of the barb-shaped end b b', from whence the spring C extends through the round part b2 and is secured to the casting B by a screw, Cor othersuitable means. The

casting B is only partially iilled by the whif- V etree A,and a recess is thus provided for the movement of the spring C, as hereinafter set forth. As the trace is moved toward the round part b2, provided as abearing for the i same, it will cause a vertical movement or" the spring O by engaging with and passing over its inclined head O', when the spring will return to the position shown, and the springf head C will secure the connection of the trace and whifletree until thetrace is intentionally removed, which may be done by pressing the head C inward and giving the trace lateral movement over the barb-shaped head b b.

Having explained the features of my improvement, what I claim as new,and desire to L secure by Letters Patent, is-

'Ihe casting B, having barbed-shaped end b b and adjacent circular formation` b2 for` InA testimony whereof I aix my signaturein presence of two witnesses.
